# Max Maths, Year 4, Work Book, Reading and making bar graphs

The Max Maths Year 4 Workbook offers a variety of exercises to help students practice reading and creating bar graphs. In one activity, students are presented with a bar graph that illustrates the favourite leisure activities of Samir's class. The graph categorises leisure activities such as playing sport, chatting online, reading a book, and watching television, and shows the number of learners who prefer each activity. Students are tasked with interpreting the graph to answer questions about the popularity of these activities, such as identifying how many students prefer to play sports, which activity is least and most popular, and comparing the number of learners who like reading to those who enjoy watching television.

Another exercise involves a bar graph representing the maths quiz results of Class 4D. Students must determine the total number of learners in the class, identify which grade was the most common, and make comparisons between the numbers of learners who received different grades. This includes verifying statements about the relative frequency of grades and calculating the sum of learners who achieved specific grades. Additionally, the workbook includes exercises where students must complete bar graphs based on given data tables, such as sales at a computer store and the colours of cars passing by a house. Lastly, there's an activity that involves drawing bar charts to represent average rainfall in various cities, using two different scales, and then assessing which scale is more effective for the data presented.
